摘要

Pinus radiata is a highly valued conifer because of its timber production and its value as a reforestation plant. To increase production, nurseries currently use a nutritional method based on mineral fertilizers high in macronutrients. This produces individual trees which are unbalanced in size and more likely to suffer infections from phytopathogenic fungi. In this paper, the effect on plant and soil of applying an aerated compost tea (ACT) is compared to a conventional fertilizer. Biometric measures of pines, their nutrient and pigment concentrations, soil physical-chemical parameters and microbial composition of the rhizosphere along with its enzymatic activity were analyzed. The results reveal that the physical-chemical parameters of the soil are suitable for plant growth in all the treatments (pH 8, maximum EC of 0.07 dS m(-1) and +239 mV of E-h), and high phosphatase activity was detected in the peat fertilized with aerated compost tea. In addition, the microorganisms developed in peat with ACT showed greater Pseudomonas spp. and fungal diversity. Pines fertilized with compost tea showed greater radicular development, proportionate distribution, higher photosynthetic pigment and total potassium concentrations, a higher yield of PSII and a greater photosynthetic assimilation rate than conventionally fertilized and unfertilized pine plants. Therefore, ACT could be used in the production of forest plants without compromising their productivity.
